Grilled London Broil with Caramelized Red Onions for a Picnic #SundaySupper

Grilled London Broil with Caramelized Red Onions for a Picnic #SundaySupper

Call this the conclusion to the London Broil dish I published this past Wednesday. In the post, I profiled a dish that appears in one of Rachael Ray's cookbooks promising to return with an updated (hopefully superior) dish. In addition, this dish is for a #SundaySupper event so I need to explain how this ties into this week's theme.

From a technical standpoint, I like this dish better. First, it's seasoned simply with salt and pepper instead of marinated. Secondly, it's grilled to achieve a better sear instead of broiled. Believe it or not, I actually simplified the accompaniment to the London Broil but it tasted better. From a #SundaySupper standpoint, this week's theme is picnic foods to celebrate the American Independence Day holiday hosted by Jane of Jane's Adventures in Dinner (Thanks, Jane!) later in the week. I like it for summer barbecues because London Broil is generally a cheaper cut of beef that doesn't sacrifice flavor and can feed a lot of people. Furthermore, it can be grilled quickly so there's more time to spend with guests at your barbecue.

I must confess. The onion component of this dish was one of my first success as a food blogger several years ago with my first website. Mrs. Stuntman requests it often. In this case, the balsamic vinegar brings out the sweetness of the red onions that complements the beef well.

The Challenge

Prepare a dish inspired by a Rachael Ray recipe

The Source

I reused the flank steak method from a dish I published last year and adapted the caramelized red onions from epicurious.


2 tablespoons extra-virgin olive oil
2 tablespoons unsalted butter
3 to 4 large red onions, halved, then sliced thin
2 teaspoons balsamic vinegar
Kosher salt
Freshly ground black pepper
1 2-pound London Broil
1 tablespoon Italian parsley, chopped (for garnish)


1. Finish the mise en place. If using an outside charcoal grill, prepare and preheat it. Bring the London Broil to room temperature by setting it out on the counter for no more than 30 minutes. Season the Broil with kosher salt and freshly ground black pepper.

2. Caramelize the onions. Melt the butter in the olive oil in a large non-stick skillet over medium heat. Add the onions and cook until golden brown, stirring frequently, approximately 30 minutes. Add in the balsamic vinegar and season with kosher salt and freshly ground black pepper, to taste.

3. Prepare the London Broil. Place the London Broil under direct heat if using a charcoal grill, or under medium high heat with a gas grill or grill pan, 6 minutes per side for medium rare but test for doneness. Set aside and let it rest to allow for carryover cooking for 5 to 10 minutes while you finish the onions. Slice the London Broil thinly across the grain for tender pieces. To plate, serve family style garnished with parsley.


I plated differently for this post but it was still delicious and better than Rachael Ray's recipe.

  17. I love caramelized red onions so much I always have to make a double batch because I have a habit of eating it out of the pan as it is cooking. :)
